Question

A car factory produces 100 cars in a day. If c is the total number of cars produced in d days, which equation represents the number of cars as a function of the number of days?
d = f(c) = 100c
d = f(c) = 100 + c
c = f(d) = 100d
c = f(c) = 100d
d = f(c) = 100 – d

Answer 1

If c is the \(\color{red}{total ~number}\) of cars produced in d days.
What does this tell you?
What is the output of the function, Is it c or d?
What is the input of the function, is it c or d?

Answer 2

Member, a function is a set of rules that consists of an input and an output, for example
y=f(x)=mx+b
y is f(x) which is the output in the function.
x is the input in the function.

Answer 3

The output is d.

Answer 4

Is it a ?

Answer 6

I already chose the 3rd one.

Answer 7

\(\color{red}y ~as~ a~ function ~of~ \color{blue}x\) is writing the equation as
y=mx+b
So, \(\color{red}{the~ number~ of~ cars}\) as a function of \color{blue}{ the~ number ~of ~days~\)
y is the number of cars, and according to the question that represents c
x is the number of days, and according to the question this represents d

Answer 8

c = f(d) = 100d ?

Answer 9

That's right

Answer 10

Thank you! Can you help me out with another?

Answer 11

Have you tried working on it?

Answer 12

Yes, actually.

Answer 13
